I live in Seattle. I get really depressed from December-February due to the lack of sunshine, and I've found it to be a more difficult place socially compared to other cities I've lived and worked in. To the point where I have frequently thought about leaving.
That said, I played beach volleyball all day yesterday with some friends as the sun set over the Olympic mountains in the background, and it was greatness. But it took me a couple of years to find my place.
Happy as can be at the moment, but it's odd how the gray can send me into a spiral of inward reflection that drives me nuts. Everyone posts the beautiful pictures of Mount Rainier and sunsets, which are gorgeous, but half the year you can feel lethargic and go into a hibernation mode which messes with your head if you don't have a strong social circle already.
